| 摘 要： | 提出了一种基于迭代误差分析法(IEA)的异常检测算法。IEA算法能够提取图像中有代表性的光谱信息,可为异常检算子的构造提供端元信息。对基本的IEA算法进行了改进,使它能够区分背景端元和异常端元。算法适合在没有先验光谱信息条件下检测高光谱图像中的小目标。

| Abstract: | An approach of hyperspectral anomaly detection based on iterative error analysis(IEA) is presented.A set of special spectra which can be extracted by using IEA are important priori information in anomaly detection algorithm.The basic approach of IEA is improved and it can discriminate between background endmembers and anomaly endmembers.The method adapts to detect small targets without any spectral priori information. |
